Answer:

x = 30

Step-by-step explanation:

Given is an irregular pentagon.

The sum of the exterior angles of an irregular polygon equals 360 degrees.

Therefore,

x° + 2x° + 2x° + 4x° + 3x° = 360°

12x° = 360°

12x = 360

x = 360/12

x = 30

yuradex [85]

Answer: $\mathbf{341 km}$

Step-by-step explanation:

Given

James takes off from Cooma and flies 452 km to south

after that he travels $37^{\circ}$ East of North to reach east of Cooma

Suppose he is $\mathbf{x}\ km$ from Cooma

Form the figure, it can be written

$\Rightarrow \tan37^{\circ}= \dfrac{x}{452}\\\\\Rightarrow x=452\tan 37^{\circ}\\\Rightarrow x=340.6\ km\approx 341\ km$

Thus, James is $\mathbf{341 km}$ east to initial position.
